Abstract

Apparatuses are provided for manufacturing a rod member for a cigarette filter element. Each rod member defines a longitudinal axis and includes a generally longitudinally-extending filter material and a plurality of objects disposed therein along the longitudinal axis. Such an apparatus comprises a rod-forming unit configured to form a continuous supply of a filter material into a continuous cylindrical rod member. An object insertion unit is configured to introduce a plurality of objects into engagement with the rod member. A rod-dividing unit is configured to divide the rod member into a plurality of rod portions such that each rod portion includes a plurality of the objects. Associated methods are also provided.

First claim

That which is claimed:

1. A method for manufacturing a rod member for a cigarette filter element, each rod member defining a longitudinal axis and including a generally longitudinally-extending filter material and a plurality of objects disposed therein along the longitudinal axis, the method comprising:
forming a continuous supply of a filter material into a continuous cylindrical rod member using a rod-forming unit;
inserting a continuous chain of objects into the filter material of the rod member using an, the continuous chain of objects being disposed at predetermined positions within and along the filter rod; and
dividing the rod member into a plurality of rod portions, and severing the continuous chain of objects, using a rod-dividing unit, such that each rod portion includes a plurality of the objects.

2. A method according to claim 1 further comprising:
receiving the rod member having the continuous chain of objects disposed therein at a garniture unit; and
circumscribing a longitudinal periphery of the rod member having the continuous chain of objects disposed therein with a continuous supply of plug wrap so as to form a continuous filter rod.

3. A method according to claim 2 wherein forming a continuous supply of a filter material further comprises:
receiving the filter material at a first receiving port of a tongue portion; and
discharging the rod member having the continuous chain of objects therein through a discharge port of the tongue portion.

4. A method according to claim 3 wherein introducing a continuous chain of objects further comprises introducing the continuous chain of objects through a second receiving port of the tongue portion, the second receiving port being discrete from the first receiving port, into the rod member.

5. A method according to claim 3 wherein forming a continuous supply of a filter material further comprises feeding the filter material to the tongue portion using a stuffer jet device disposed upstream of the tongue portion.

6. A method according to claim 3 wherein introducing a continuous chain of objects further comprises:
receiving a tube through a second receiving port of the tongue portion, the second receiving port comprising an aperture defined by the upper face; and
delivering the continuous chain of objects through the tube to the filter material.

7. A method according to claim 6 wherein delivering the continuous chain of objects further comprises delivering the continuous chain of objects through the tube, the tube being configured to extend into the filter material, as the filter material is advanced between the first receiving port and the discharge port of the tongue portion, such that the continuous chain of objects is introduced into the filter material therethrough.

8. A method according to claim 1 wherein inserting a continuous chain of objects further comprises:
supplying a continuous chain from a bobbin having the continuous chain wrapped thereabout, each object being attached to an adjacent object so as to form the continuous chain; and
inserting the continuous chain into the filter material using an inserter device operably engaged with the bobbin so as to receive the continuous chain therefrom.

9. A method according to claim 1 wherein introducing a continuous chain of objects further comprises:
receiving objects within a tubular member such that the objects are disposed therein; and
introducing the tubular member having the objects therein into the filter material using an inserter device operably engaged with the tubular member.

10. A method according to claim 1 wherein inserting a continuous chain of objects further comprises:
supplying a continuous elongate member from a bobbin having the continuous elongate member wrapped thereabout, the continuous elongate member having objects attached thereto; and
inserting the continuous elongate member and the objects into the filter material using an inserter device operably engaged with the bobbin so as to receive the continuous elongate member therefrom.

11. A method according to claim 10 wherein supplying a continuous elongate member further comprises supplying the continuous elongate member comprising a continuous strand having the objects attached thereto.

12. A method according to claim 10 wherein the continuous elongate member has a laterally-extending width, and the method further comprises continuously width-wise wrapping the elongate member about the objects attached thereto using a wrapping device, wherein inserting the continuous elongate member further comprises inserting the objects wrapped by the continuous elongate member into the filter material.

13. A method according to claim 10 wherein the continuous elongate member has a laterally-extending width, and the method further comprises continuously width-wise wrapping the elongate member about the filter material so as to engage the objects therewith, using a garniture device, prior to the continuous rod being subdivided.

14. A method according to claim 1 wherein introducing a continuous chain of objects further comprises:
supplying a continuous elongate member, discrete from the plurality of objects, from a bobbin having the continuous elongate member wrapped thereabout; and
introducing the continuous elongate member into the filter material.

15. A method according to claim 14 wherein supplying a continuous elongate member further comprises supplying a continuous elongate member comprising a continuous strand.
